The video streams provided by webcams can be used for a number of purposes, each using appropriate software: Most modern webcams are capable of capturing arterial pulse rate by the use of a simple algorithmic trick.

Researchers claim that this method is accurate to ±5 bpm.

Has anybody else out there gotten similar requests recently?

A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network.

Webcam can be added to instant messaging, text chat services such as AOL Instant Messenger, and Vo IP services such as Skype, one-to-one live video communication over the Internet has now reached millions of mainstream PC users worldwide.

Webcam features and performance can vary by program, computer operating system, and also by the computer's processor capabilities.However, there was no "send a message" icon, and without that, I just decided to ignore the request -- though, all other things being equal, the idea of an attractive woman as a Facebook friend is not unattractive (!) to me, as would be the case, I assume, with most guys.(For all I know, similar requests, with attractive guys, are being sent to women.) Once you accept their friend request, they gain access to a lot of information about you, to be used for who knows what purpose.And once you've accepted the friend request, they get access to all your friends, so they can send these requests to all your friends, and the page will note that the requestee has a friend in common, increasing the chance the requestee will accept the request.
